By default, Airbnb, Smoobu and most other portals, work with a base rate for the minimum number of guests and allow you to add an extra fee for each additional guest.
By default, Booking.com (and sometimes Expedia) work with a base rate for the the maximum number guests, and reduce the price for each guest below the max.
How to correct this?
Option 1 - Do it yourself
1. Go to the Booking.com Extranet.
2. Click Rates & Availability / Pricing per guest.
3. Adjust the Base Occupancy at the top.
4. Scroll down. Toggle on (at the right) and enter an amount to increase by. You can also increase by %.
5. Do this for all Rate Plans
Option 2 - Contact Booking.com
You may also call Booking.com and/or Expedia and invert this configuration.
In this way, your standard base rate will be established for the minimum number of guests, with the same criteria in all portals, and you can easily send the standard rate from Smoobu.
We instead recommend to configure your Standard Rate (other rate plans) to increase the price for additional guest.
And now, if you have not already done so, please enter your prices in Smoobu to synchronize them with your portals. Read our guide on how to synchronize prices and minimum stay.
Remember that for Booking.com and Expedia, the price per additional guest is managed directly on their Extranets, while for Airbnb it's managed from Smoobu.
